Sennheiser CHG 70N-C + PSU KIT Two-Bay Network-Enabled Charger for EW-DX Series - 700333

Product Overview

The Sennheiser CHG 70N-C + PSU KIT is a professional two-bay network-enabled charger designed for the EW-DX wireless system, bundled with an external power supply for a complete, installation-ready solution. It simultaneously charges up to two EW-DX SK bodypack or EW-DX SKM/SKM-S handheld transmitters — or two standalone BA 70 batteries — making it the ideal charging hub for touring, broadcast, and permanent AV installations. Network monitoring and remote control via Sennheiser Control Cockpit software or third-party media control systems over an RJ45 Ethernet connection give system administrators full visibility into charge status from anywhere on the network. The included NT 12-35 CS power supply means the CHG 70N-C is ready to deploy immediately out of the box.

Product Description

Professional wireless audio operations demand reliable, managed charging infrastructure — especially in broadcast facilities, conference centers, and touring rigs where transmitter readiness directly impacts production uptime. The Sennheiser CHG 70N-C + PSU KIT was designed to meet that demand head-on for the EW-DX wireless platform.

The charger's two independent bays each accept an EW-DX SK bodypack transmitter, an EW-DX SKM or SKM-S handheld transmitter (with BA 70 battery installed), or a bare BA 70 battery. A full charge takes approximately 3.5 hours, with an 80% charge available in roughly 2 hours for rapid turnaround between shows or sessions. A color LED indicator at each bay provides at-a-glance charge status so operators always know the state of their batteries without needing to interact with software.

Network integration is where the CHG 70N-C distinguishes itself from conventional chargers. An RJ45 Ethernet port supports Sennheiser's Media Control Protocol, enabling full remote monitoring and control via Sennheiser Control Cockpit — the same centralized management platform used across the EW-DX, Digital 9000, and other professional Sennheiser wireless systems. The charger is also compatible with third-party media control systems, making it easy to integrate into a Crestron, AMX, or Q-SYS controlled AV environment.

Power flexibility is another key advantage. The CHG 70N-C can be powered by the included NT 12-35 CS external power supply (12 VDC at 3.5 A) or via Power over Ethernet (PoE, IEEE 802.3af Class 0) — eliminating the need for a separate power run to the charger location. Up to five CHG 70N-C units can be cascaded on a single network connection and power supply, dramatically simplifying large-scale multi-bay charging deployments in broadcast trucks, rental houses, or permanent boardroom installations.

The included PSU transforms the CHG 70N-C into a complete, self-contained solution. No separate ordering of power supplies is required — open the box, connect power and network, and you are charging and monitoring immediately. The compact physical footprint (200 x 116 x 104 mm) ensures it fits neatly in equipment racks, on shelves, or in custom-built charging stations.

Technical Specifications

Frequently Asked Questions

Q: What transmitters and batteries are compatible with the CHG 70N-C?

The CHG 70N-C charges EW-DX SK bodypack transmitters, EW-DX SKM and SKM-S handheld transmitters (with BA 70 batteries installed), and standalone BA 70 batteries.

Q: Is a power supply included in this kit?

Yes. The CHG 70N-C + PSU KIT includes the NT 12-35 CS external power supply, so no additional purchasing is required. The charger can also be powered via PoE if a PoE-capable network switch is available.

Q: How long does a full charge take?

A full charge takes approximately 3.5 hours. An 80% charge is available in roughly 2 hours, supporting faster transmitter turnaround for back-to-back events or sessions.

Q: Can I monitor the CHG 70N-C remotely over the network?

Yes. The RJ45 Ethernet port supports Sennheiser's Media Control Protocol, enabling remote monitoring and control via Sennheiser Control Cockpit software or compatible third-party control systems such as Crestron, AMX, or Q-SYS.

Q: Can multiple CHG 70N-C units be cascaded together?

Yes — up to five CHG 70N-C units can be cascaded using a single network connection and power supply, making large-scale deployments efficient and cost-effective.

Q: Can the CHG 70N-C be powered via PoE without the included PSU?

Yes. The unit supports Power over Ethernet (IEEE 802.3af Class 0), so it can be powered directly from a PoE-capable network switch without the external power supply, providing clean single-cable installation.

Q: Does the CHG 70N-C work with older EW series transmitters?

The CHG 70N-C is designed specifically for the EW-DX series transmitters and BA 70 batteries. It is not designed for use with EW-D, EW 300 G4, EW 500 G4, or other previous-generation Sennheiser transmitters. Contact Creation Networks to identify the correct charger for your system.
